Race Series Engine Case Covers have been specifically developed in collaboration with selected high level BSB race teams. In addition to the existing R&G Engine Case Cover range comes R&G's spec Race Series Engine Case Covers, specially developed at the request of race teams and riders alike. They include a replaceable puck or slider on the impact face, giving the case not only more meat to grind through to further enhance the protection offered by a standard R&G Engine Case Cover but also offering an easy low-cost fix should you only have a ""minor"" slide, crash or drop. Fits: BMW S1000RR 2010-2016
